fix(misc): Fix getExactDuration behaviour when given a precision parameter (#103958)

This PR fixes a bug visible on some [alert
pages](https://sentry.sentry.io/issues/6827154726/open-periods/?project=4507946704961536&referrer=event-or-group-header).

The predicate in the ternary fails to return true when it's supposed to
because it's matching the plural and singular version of a word. e.g. in
the above case, it doesn't match `minutes` and `minute` so it recurses
and appends a "0 minutes".

Instead of comparing `minSuffix` and `suffix` we now just compare
`precision` (the minimum unit) and the unit of the block.
