bug#58165: [Patch] [GNU ELPA] rcirc-color: Allow recoloring nicks

[Thuna]

I think rcirc-color should allow a nick to be "recolored" with the
command `/color nick', instead of signalling an error as it does now.

This is useful, for example, when two similar nicks are assigned the
same color but there's no specific color you want to reassign to either
of them.
