fix: communication-sms: remove mocha arrow functions (#26659)

### Packages impacted by this PR

`sdk\communication\communication-sms`

### Issues associated with this PR

#13005 

### Describe the problem that is addressed by this PR

The existing mocha tests for the `sdk\communication\communication-sms`
made use of the arrow syntax for callback functions. Mocha recommends
not to do this because you lose access to the mocha context
(https://mochajs.org/#arrow-functions).

### What are the possible designs available to address the problem? If
there are more than one possible design, why was the one in this PR
chosen?

The reason for utilizing the function keyword instead of an arrow syntax
to write the callback functions in these mocha tests is to maintain
access to the mocha context.

### Are there test cases added in this PR? _(If not, why?)_

No additional test cases were added in this PR as the change only
required modifying existing test cases.
