Is your feature request related to a problem? Please describe.
Need open source functional tests for certifiability

Describe the solution you'd like
Add additional checks to functional tests for cFE Get Table Information APIs.

#1734 adds basic functionality checks and error condition checking, but doesn't check everything.

The following list contains things that are not currently tested, but probably should be

CFE_TBL_GetStatus:

• Test that pending update, validation statuses are returned at the correct time

CFE_TBL_GetInfo:

• test NumUsers increments after the table is shared
• test Crc is valid
• test LastFileLoaded is correct after loading a file
• test TableLoadedOnce updates after loading data
• test FileCreatedTime makes sense
• test TimeOfLastUpdate is correct

CFE_TBL_NotifyByMessage:

• Test messages are actually sent with correct message id, cc, parameter

Describe alternatives you've considered
N/A
