Use A higher prime number in AppLnk

Somehow the Launcher triggers issues with libqpe and MimeType.

Due the mix of calling MimeType::clear, MimeType type(doclnk.linkFile()),
MimeType::clear
the registration of Application was cleared and not reentered due the
inner static variable in MimeType::init which was set.
Now make sure that if we clear that we will reenter the Application in all cases!
