Describe the contribution

• Fixes Missing test for one branch in SAMPLE_APP_Process() #199
  • Tests added to cover missing branch.
    • The test calls SAMPLE_APP_Process() with a seeded failure from CFE_TBL_ReleaseAddress().
    • The desired branch flow is confirmed by checking for the expected 3 additional calls to CFE_ES_WriteToSysLog() (in this function, only this specific path would add 3 additional calls to CFE_ES_WriteToSysLog()).
