I agree. As the driver manual the OP linked to says on page 78, "Do not pass on the right – Do not pass on the right side of vehicles in traffic at intersections. Motorists turning right may not look for, or see, a bicycle passing on the right."
As far as how to avoid the situation in the future, I'd say slow down. I have a few spots I ride where cars want to make a right and I use it as an opportunity to grab a sip of water. I let the cars go and merge in as there is an opening. Sometimes this is further back and I make cars go slow behind me (i.e. I take the lane), other times it is at the last second. Regardless, I have found going slow, and being ready to speed up and take the opening when it is there, works for me. YMMV.
The mirror is probably a good idea too, although I haven't found them as useful for me as other people here have.
