lisa.analysis.base: AnalysisHelpers.plot_method(): always_save=False

Disable automatic saving of plots by default when no file path has been set.

Most of the calls to plot methods are either done in scripts/tests where the
filepath is set, or from notebooks where the interactive integration of
matplotlib is used. In these scenarios, automatic plot saving is just creating
files around that nobody needs.
