Fix None prompt until manually changed

The GeminiClient's constructor expected set_prompt to return the prompt,
while the function directly mutated it without returning anything.

This manifested as having "None" as prompt instead of the default "ON>", until
entering the offline command.

This patch both fixes the constructor by not setting self.prompt to the
result of GeminiClient.set_prompt, *and* make that function return the
prompt as well. Each of those is a separated hunk, feel free to only
apply whichever feels best (though applying both should warrant any
future mistake of the sort).
