QDoc: Check if index file was already inserted in list.

Previously it was possible to insert exactly the same index file in the
map twice by specifying an -indexdir which is the same as -installdir.
Probably you can also have two indexes with the same name that happen to
have the same creation time, but changes of that happening are slim to
none.
