Title: finalizes `tap` deprecation

## motivation

We want to deprecate the tap method because its arguments are confusing. It has been replaced with `wait_tap`.

The refactoring of methods out of operations.rb to core.rb broke the rspec tests.

Updated changelog with deprecation message.

Updated a flickering rspec test.
