Fix in gst_tag_merge_strings_with_comma

After creating a test ogg file and inserting multiple artist fields in it, I
ran a program written by me that extracts the metadata from a file via
GStreamer (using gst_tag_list_get_string for the string fields), and got the
following oddity:

$ vorbiscomment -w -t "ARTIST=foo" -t "ARTIST=bar" -t "ARTIST=baz" -t
"ARTIST=qux" -t "ARTIST=quux" test.ogg
$ ./metadata test.ogg
artist: foo, bar, bar, bar, bar

i.e. after the second occurrence of the artist tag, the second field value is
always used. The solution is very simple (just one character in
gst/gsttaglist.c) and the patch is attached.
