A_TE_HALT was being filtered incorrectly

• which means transitions could still be active during the join process
• which means resource actions could be overwritten (lost) during the join
• which means resources could be active more than once
• which is the bug I tried to *remove* yesterday

We can detect this with the R_IN_TRANSITION register flag

• Complain loudy if it's set during a join (so we're sure its fixed)
