fix: install and download events are not reliably delivered

[eseidel]

Right now we have 3 separate places where we send patch events.

The queue:

updater/library/src/updater.rs

Line 350 in b2d5ece

let result = crate::network::send_patch_event(event, &config);

Within update (download):

updater/library/src/updater.rs

Line 431 in b2d5ece

let report_result = crate::network::send_patch_event(event, &config);

Within launch success (install):

updater/library/src/updater.rs

Line 635 in b2d5ece

let report_result = crate::network::send_patch_event(event, &config_copy);

None of them retry. It's also kinda silly to have 3 methods.

We should probably always use the queue, and just have multiple places where we try to flush the queue. We should also probably only remove events on success or queue overflow.
