Add tests for getIpAddrStr

[sirknightj]

Issue #, if available:

• N/A

What was changed?

• Unit tests were added for GetIpAddrStr in Network.c

Why was it changed?

• According to codecov, this method is already covered, however I was unable to locate a test that validated correctness of the out parameter buffer.
• Since we rely on logs heavily during debugging, want to add additional checks to make certain that the IP addresses printed are correct and never accidentally broken in the future.

How was it changed?

• Added additional checks for getIpAddrStr, which is a toString for the IP addresses.

What testing was done for the changes?

• Ran the tests locally, they pass. Source code wasn't touched.
