Show more info about Execution error: Assert Exception: static_cast<size_t>(tag) < count()

Description

When trying to transact with an older version of cli_wallet (E.G. 5.0.0) on the current chain (version 6.x), this error is returned:

Execution error: Assert Exception: static_cast<size_t>(tag) < count()

Reported by multiple users.

The error appeared after explicitly set fee schedule for operation number 64-74. It disappeared after the explicit values got removed from fee schedule.

I think the error is generated by this code:

bitshares-core/libraries/protocol/fee_schedule_calc.cpp

Line 47 in ac1cfc0

params.set_which(current_op);

Still trying to stably reproduce.

It is better to show more info for easier diagnosis when such error occurs.
