[BUGFIX] Remove $scheme from LegacyLinkNotationConverter::resolve()

The code block using $scheme is never reached, because there is already
an elseif condition further above, that is true for all urls containing
":".

The last else block even states in the comment:
"special handling without a scheme"

Therefore the variable is removed to remove a bit of complexity from the
function.
