Mike Bayer 61384fd0e5 - Fixed a regression caused by 🎫2976 released in 0.9.4 where ...

the "outer join" propagation along a chain of joined eager loads
would incorrectly convert an "inner join" along a sibling join path
into an outer join as well, when only descendant paths should be
receiving the "outer join" propagation; additionally, fixed related
issue where "nested" join propagation would take place inappropriately
between two sibling join paths.

this is accomplished by re-introducing the removed flag "allow_innerjoin",
now inverted and named "chained_from_outerjoin".  Propagating this flag
allows us to know when we have encountered an outerjoin along a load
path, without confusing it for state obtained from a sibling path.
