Remove redundant `test_too_many_binds`

with `ActiveRecord::BindParameterTest#test_too_many_binds`

sqlite adapter has its own `bind_params_length`, `ActiveRecord::BindParameterTest#test_too_many_binds` respects it.

* Modified `ActiveRecord::BindParameterTest#test_too_many_binds` to show `bind_params_length` value
