Just to be more clear:

An example where one sees the problem, at rate=44100Hz if you start at t=0,
after 1 sample you will be at  t = 1/rate = 22675.74 ns. If you get it with 
gst_util_uint64_scale_int(), that's a 22675. But with 
gst_util_uint64_scale_int_round() you get 22676, which is arguably the 
best one.

As for the patch, it works because in audiotestsrc the timestamps are always
computed from the "bytestamps", that is, how many bytes away we are from
timestamp=0 (stored in a variable called "next_sample").

Finally, I've run the unit tests ("make check" in gst-plugins-base) and they
all passed with no error.
