Clear url parameters for entity search tabs

[Atmire-Kristof]

References

• Fixes Sort query param persists between switching search tabs on entity page, breaking search if not configured #2729
• Fixes Browse by metadata: If you already selected a value to browse by (value in url) & then search (startsWith) doesn't work #2739
• PR for 7_x: 7.x - Clear url parameters for entity search tabs #2735

Description

Clears all url parameters when switching search tabs on entity pages to avoid using non-existent filters/sort/configurations/pages etc. on the new search tab.
Clears url parameters and component properties when applying startsWith or value on browse-by pages, avoiding a conflict between the two described in #2739

Instructions for Reviewers

How to test entity pages:

• Visit an entity item page containing more than one search tab, with one search tab containing a filter or sort option not available on the other tab
• Select a value for that filter/sort option
• Click the other tab
• All parameters except the tab identifier should be cleared and search is still functional
• Perform the same test, but one tab containing more pages of results than the other, selecting the last page and clicking the other tab, you should end up on the first page of the new search tab

How to test browse-by pages:

• Visit a browse-by metadata page (e.g. subject)
• Select a value
• Search for a different value. It should clear the previous value and ONLY display the "startsWith" value you just entered, as well as any results matching it
• Selecting a value after a search should also clear the "startsWith" parameter, in order for only the clicked value to be visible

Applied an additional fix for #2739, since it's related to the same issue of clearing url parameters.

@Atmire-Kristof : I tested/reviewed this today. While, I can verify it fixes both #2729 and #2739, this PR is currently failing several existing specs/tests in StartsWithDateComponent. Please update this PR to either pass those tests or fix those tests.

I don't think #2739 should be considered a bug. The second parameter 'startWith' is used to filter the list of items by title that have the previously selected value. For example, if you select the subject 'financial therapy' on the current demo site (https://demo.dspace.org/browse/subject?value=financial%20therapy&bbm.return=5), you can then filter this list by titles that start with 'Book' (https://demo.dspace.org/browse/subject?value=financial%20therapy&bbm.return=5&bbm.page=1&startsWith=Book).
