Fixed an issue in :func:`.unitary_to_gate_sequence` which caused unitary
decomposition in the RR basis to emit two R gates in some cases where the
matrix can be expressed as a single R gate. Previously, in those cases you
would get two R gates with the same phi parameter. Now, they are combined
into one.
