Undo: clear undo history on load / import

Keeping undo-history across load makes little sense. The user was
expressly reminded that they have unsaved work.

For import (from other logs or the dive-computer) an undo-functionality
would be desirable. Nevertheless, this is rather complex since
new and old dives are merged. Implementation would require a finer
backend<->undocommand interface. Thus, leave this for now until more
experience with the undo system is acquired.
