Tag Alias: wristband -> wrist_bands

Aliasing wristband -> wrist_bands.

Reason: Actually a alias reversal and clean up from:

wrist_band (0) → wristband (1720)
wristbands (0) → wristband (1720)
wrist_bands (0) → wristband (1720)

Re-pluralizing the tag would put it back in line with our policy on natural pairs, and re-introducing the space would put it in line with all the other {wrist*} tags we have.

It's arguable that wrist bands "naturally" come in pairs, it seems to be nearly as common to wear only one.

I think the wristband tag is fine as it is, a compound noun and in single form. It's easily fit in line with other *band searches too.

Yeah I'm not convinced of natural plural here.
