Entering a somethign in the 'Path field' triggers the
`_path_changed` signal being triggered.
This in turn calls Globals::localize_path(const String& p_path) with the
currently entered string.
localize_path then is replacing backslashes with slashes and calls
afterwards `String::simplify_path`
String::simplify_path is checking wheter a string starts with:
- res://
- local://
- user://
If any of those is true it removes this section.
However, if any of the first letters of those are matching begins_with
returns true, which is wrong. It should only return true if the whole
string is matched at the beginning.
This caused the whole desaster and lead localize_path into an endless loop
because out of `u` suddenly became user:// which it then tried again to
localize and so on.
This fix, fixes the root of the problem which is begins_with which should
not return true if not the whole search string was matched.
