fc77345bec breaking change. Enforce append semantics everywhere for parameter updates #5744 
Replace semantics doesn't work with assumptions made elsewhere in code.
The remedy is to apply append (override) semantics for parameter changes.

d06f4bd337 Fix reset of params_ref in solver 
params_ref is not a ref, and params_ref::reset is not ref::reset.

params_ref::reset resets the params object being pointed to by
params_ref.

A proper way to reset a params_ref as a reference is to assign an
empty params_ref object to it.
