Service History - "Calc as of" Date

[dcieslicki]

1. Go to Create New Account > Service History or Account Details > Service History.
2. When we enter data in the "calc as of date" it should remain the same date until we proactively hit the interest update button or we enter another calc as of date in that same area.
3. It should not automatically update once we go out of the account.
4. We do not want the system to automatically update interest in the billing summary or the billing statement. This happened on all the scenarios I entered today.

I believe this dupes #66.

Ok, as long as it's fixed that's all that matters
