If the reports directory doesn't exist, writing the timeseries report should just fail silently. Right now it generates a warning. For example, If the user requests that no reports should be generated
p = om.Problem(model=om.Group(), reports=False)
Then bokeh_timeseries_report.py should just not generate the trajectory results report without issuing the warning
bokeh_timeseries_report.py:251: OpenMDAOWarning:Reports directory not available. reports/brach/traj0_results_report.html will not be created.
