Fail to load upstream extracts from physical bioassays when inheriting annotations

[Nicklas Nordborg]

This is the same issue as #1805, but appear in the "Inherit annotations" tab in the edit dialog of any derived bioassay that has a link to an extract.

Extracts that are between the physical bioassay and the linked extract is missing from the dialog. For example, consider the following structure with 4 parent extracts that are pooled in two separate pools and put on a single physical bioassay and then split into 2 derived bioassays.

Extract 1 -> Pool 1 -> Physical BA -> Derived BA 1
Extract 2 -> Pool 1 -> Physical BA -> Derived BA 2
Extract 3 -> Pool 2 -> Physical BA -> Derived BA 3
Extract 4 -> Pool 2 -> Physical BA -> Derived BA 4

If the Derived BA 1 has a link to Extract 1, it will not be possible to inherit annotations from Pool 1. Removing the link will enable inheriting from all pools and all extracts which is not correct either.
