make GetChannelByName take teamId first (#9134)

* make GetChannelByName take teamId first

I think it is more natural to accept `teamId`, then `channelName`,
given the pattern followed by other Plugin API methods and even the SQL
Store itself. The App layer seems unusual in accepting `channelName`
first.

This also re-generates the mocks fixing the parameter order for the
recently added `UserStatus` APIs.

* add GetChannelByNameForTeamName
