Fix T83064: Missing tooltips, caused by string property search button

When a searchbox-button for string properties (e.g. to reference a vertex
group) was created, and a value was set, the tooltip timer would constantly get
cancelled.
That was because the code to validate the current value
(`ui_but_search_refresh()` - early exists for non-string properties) would call
a helper function to update the search results (`ui_searchbox_update_fn()`),
which always reset tooltips. Resetting them in the helper makes sense, for as
long as the searchbox is open. But while it's not, and we just validate the
current value, it shouldn't do this.

This was also noticable in the output settings of dynamic paint, and probably a
number of other cases (especially with script UIs which tend to use string
properties more often).

Likely caused by de53c039adb4.
