Always allow custom wildcards

Removed unnecessary restriction that custom wildcards are only possible when 'before' and 'after' are false/disabled.
This allows queries like:
Text LIKE '%This _s _ T%t%', when "This ?s ? T*t" was entered as search query, while 'before' and 'after' are true.
One or the other can be false, too

Partly reconstructed testSubQueryEmptyCondition()

The test was very similar to testSubQueryCondition().
In the past this test looked different:

Somebody with more in depth knowledge should have a look.
Fixed one test and removed another that isn't necessary anymore since always allowing wildcards.
