`ActionError` and `IndexError` while trying to get transition states of H abstraction reactions from importer

[skrsna]

I'm getting the following errors while trying to get a TS object. Action Error for this reaction CC1=C[CH]C=CC1=O+CCCCO_CC1=CC=CC=C1O+CCC[CH]O1

IndexError: list index out of range

Both of these errors can be traced back to family.py in rmgpy. The reactions in question are scraped from importer project and were able to make a transition state in py2. I'm seeing these errors after we updated to py3.
