[FIX] Adtexts recognition - sklik is changing destination urls

we need to strip all slashes / - sklik is adding them on the end of path
jus before query:
http://www.bartas.cz?utm_source=sklik
became:
http://www.bartas.cz/?utm_source=sklik

and when you do the update, SklikApi recognized this new updated url
as anoher ad, so it was deleted and tried to create new one but this
will raise exception that ad is already in system.
