derAnfaenger 8f2fc6069d bots: Refactor and simplify bot_test_lib.py.
This commit integrates the mock_test function in
check_expected_responses and makes this function usable
for simple tests only by not allowing mock http conversations.

assert_bot_response() is now used for single message-response pairs,
resolving potential issues with multiple messages and a single http
request-response pair.

The giphy bot test file is updated accordingly.
