Issue 144 stop search

A bug fix for issue #144

The while loop will be stopped if there no table rows elements in loaded results

I check the Travis CI reports: builds for Python 3.5 and 3.7 run fine, but with Python 3.6 the build raise an exception. I don't understand why?

Wouldn't be if not geocaches_table.find_all("tr")) enough? And we might should save geocaches_table.find_all("tr") in an own variable before and use it in line 254 as well to reduce duplicate code.

Yes it could! I changed this.

I did it :-) and push the update to Github.

Please can you check my PR, again?

LGTM. I am not sure about the failing test case though, but it seems to switch between the different versions and is not really related to this change.

I added a new issue for the failing test as it seems to be unrelated to this PR, so this is ready to be merged.
