This fixes the bug uncovered by the tests added in the previous two patches. When an existing notes ref was loaded into the fast-import machinery, the num_notes counter associated with that ref remained == 0, even though the true number of notes in the loaded ref was higher. This caused a fanout level of 0 to be used, although the actual fanout of the tree could be > 0. Manipulating the notes tree at an incorrect fanout level causes removals to silently fail, and modifications of existing notes to instead produce an additional note (leaving the old object in place at a different fanout level). This patch fixes the bug by explicitly counting the number of notes in the notes tree whenever it looks like the num_notes counter could be wrong (when num_notes == 0). There may be false positives (i.e. triggering the counting when the notes tree is truly empty), but in those cases, the counting should not take long.
