Abort trap: 6

To work around this we must import tiledb before pyarrow.

I tried this before and it was not enough

• Previously I only had apis/python/src/tiledbsoma/__init__.py -- not enough
• I had missed apis/python/tests/__init__.py -- this is enough -- on this PR

See #1849 #1926 #2692 for more information.
