fix: check channel type before the guild-derivation guard (dpylogger-9)

The wrong-type channel check sat after the no-resolvable-guild guard, so a
non-TextChannel object passed without a guild raised the misleading "channel
provided without a resolvable guild" instead of "is not a text channel" - the
accurate message only fired when a guild was also supplied. Move the type
check first so both branches report the real problem.
