Fix edge case involving filter with a single wildcard

Browse source 
This fix the case of the following filter:

    trk*.vidible.tv

Not matching:

    https://trk.vidible.tv/trk/.vidible.tv

The wildcard is supposed to match any number of
characters, including zero characters. The issue
is that the code was not matching zero characters.

This is due to an incorrect comparison in
BidiTrieContainer.indexOf(), causing the code to
bail out before testing for the zero character
condition.
