Vulnarability in axios

[Mwandia]

Axios version 0.19.2 has a vulnarability to SSRF as described further in PR #3410 on the axios repo.

Motivation

This is a severe vulnarability, the dependabot has attempted to update the package in PR #4 but the several tests failed in the build pipelines

Contribution

I can manually update axios package version to the lowest version that has the vulnarability patched. Also by changing some tests to handle current response formats from africastalking APIs. For example:

• Token: test 'generates auth token' expects result to contain key 'lifetimeInSeconds' but this is not part of response
