Always try to mount in gio::Content::getGFileInfo

...and not only if the caller happens to pass in non-null ppError.  Otherwise,
calling soffice with a document URL handled by the gio UCP that is not yet
gio-mounted would silently do nothing and exit with EXIT_SUCCESS, as the first
thing the type detection code does on the URL is execute "getPropertyValues" for
"IsDocument", which calls getGFileInfo with null ppError, so a void instead of a
boolean value is returned, which then derails the type detection code to
silently fail (which is another problem that needs fixing).
