[Plot] Prevent duplicate query on bounds change

Browse Source 
Bounds change triggers a clearing of plot history, which triggers
a user interaction change, which was triggering a second query.

This change sets a flag to prevent the requery from the user interaction on
bounds change.  This flag could potentially be reused elsewhere, e.g. if we
wanted to prevent requery when not utilizing a minmax data source.

fixes #2126
