What steps will reproduce the problem?

1. Attempt to open a test case with no commands - for example a previously saved test
suite file instead of a test case file.

What is the expected output? What do you see instead?

Expected: A message informing that the test case contains no commands. If we can detect
that the file is a test suite file maybe provide the user the option to open the suite
instead.

Actual: The message 'error loading test case: no command found'
