What does this PR do?
The previous code made some assumptions about the format of the commands that were not correct, namely that they would always contain at least 1 space. This seems to be true for commands generated by the library, but not necessarily for commands given as text to the Do function, e.g. client.Do(ctx, "PING").
This results in a panic due to out-of-bounds indexing.
This commit makes the parsing code not assume this format and adds a test case to ensure it works correctly for commands with zero spaces.
