Core: Make preview work when FOO is both a variable and a prefix

Browse Source 
Make the preview of variable "FOO" work in the variable chooser when the
macroexpander also has a prefix "FOO:" defined.

The MacroExpander::isPrefixVariable method is broken in this case: It will
append ':' to the variable name if it is not there already and will thus
return true for both "FOO" and "FOO:". So avoid calling it.

In this case this does not even lead to more look-ups: As the variable chooser
uses the description of the variable as a key, it contains "FOO:<value>" for
the variable name and uses that checks whether "FOO:<value>:" is a prefix variable
or not. That is always false.
