The tags query module has a tgprop parameter to specify which properties of
the tag should be returned. One of these properties was 'name', but the
name was always included in the response regardless of whether this
property was included in tgprop.
Since most uses aren't specifying 'name' but we can assume clients are
depending on the name being included (since there's otherwise no way to
identify which tag is which), we've removed the nonfunctional 'name' as a
valid option for tgprop. This will result in a warning that 'name' is not a
valid value for tgprop for those few clients that are specifying 'name'
This change will not affect the functionality of any clients unless the new
warning somehow breaks them. It should be deployed to WMF wikis with
1.31.0-wmf.18 or later. Clients can safely stop specifying 'name' in tgprop
immediately, though, since it doesn't do anything.
