[BUG] TypeError with inspect methods=True

[thorstenkampe]

The below code gives a TypeError on a SQAlchemy engine with methods=True

import sqlalchemy as sa

engine = sa.create_engine('sqlite://')
rich.inspect(engine, methods=True)

Traceback (most recent call last):

Seems there was an attribute that was callable but failed to introspect the signature. Should be fixed in 9.8.1
