Update logged information for AutoML init #2092
Description
Minor user experience nit-pick, but there have been several times when I just instantiate AutoMLSearch and forget to call search. The output of init looks like:
automl = AutoMLSearch(X, y, problem_type="binary")
Using default limit of max_batches=1.
Generating pipelines to search over...
As a user, "Generating pipelines to search over..." makes me wait in anticipation for something to happen. However, by the time init has returned, the pipelines have already been generated. Hence, we should update logged message to something else, such as "Generated pipelines to search over." or just remove it entirely.
