fixed link deletion 

When deleting links, the js of the default theme separated ids by an escaped space ('+').
There was a trailing '+' after the ids which led to the php code detecting multiple values
even for single values. In combination with the id '0' this could led to no id found at all
and a resulting php error.

this commit fixes the behavior and adds an additional error handling and trimming to the php code.
