Fix showing `!source` on tags when tags cog is reloaded

Previously the source command checks for the source object's class after
getting it from the SourceType converter. When the tags cog is reloaded,
TagIdentifier is redefined. We were checking whether the old
TagIdentifier class (the `type()` of an instance of the old
TagIdentifier) equals the newly defined TagIdentifier class. This
returns false because the TagIdentifier class is redefined when the tags
cog is reloaded, which caused tags, correctly identified by Source
converter, to be unable to be identified in the source cog.

The fix takes advantage of the fact that the source converter could
correctly identify tags objects even after the tags cog reloads, and use
enum comparisons rather than `isinstance`/`type()` to obtain the source
type of whatever the source converter returns.

Since we're no longer using the source converter as an actual converter,
the function is moved to the source cog instead, and it still works
fine.
