Fix simultaneous source and binary package install

rpmInstallSourcePackage() grabs the transaction element with the index
of 0, which only works correctly if the src.rpm package is the only one
in the set.  That's not the case if some binary packages have been part
of the same install command in rpmInstall() so we need to make sure the
set is emptied beforehand.

Add a test to go with.
