ref-filter: fix read invalid union member bug
used_atom.u is an union, and it has different members depending on
what atom the auxiliary data the union part of the "struct
used_atom" wants to record. At most only one of the members can be
valid at any one time. Since the code checks u.remote_ref without
even making sure if the atom is "push" or "push:" (which are only
two cases that u.remote_ref.push becomes valid), but u.remote_ref
shares the same storage for other members of the union, the check
was reading from an invalid member, which was the bug.
Modify the condition here to check whether the atom name
equals to "push" or starts with "push:", to avoid reading the
value of invalid member of the union.
