Prevent expired entries search if no results returned

[droidmonkey]

• Fixes A search string is set automatically after database unlock #8626

Type of change

• ✅ Bug fix (non-breaking change that fixes an issue)

[michaelk83]

If the user initiates a search manually (doesn't matter where from), I think they'd expect to see something, even if the results are empty. I'm not entirely clear if this PR takes that into account or not.

But anyway, the real fix for #8626 would be to finish #7791 . @droidmonkey , how about including that in 2.7.4?

[droidmonkey]

The code introduced here only ends the search if no entries are found when the "next search label" variable is set. This variable is only set when performing the expired entries on unlock search. Although it looks like the gui tests are failing on search.
