Fix to OCOO rule in HO2_Elimination_from_PeroxyRadical.

For some reason this rule was not properly imported from the RMG-Java
database before.
Changed definition of OJ in Substitution_O to allow adjacent biradical.

This avoids an error where the Substitution_O family could only identify
a reaction in one direction (this family is its own reverse, so you
should be able to identify it in both directions).
