multicursor: ]C [C after clearing cursors

Problem

After clearing cursors (i.e. exiting the multicursor session), ]C [C do nothing. This seems like an unnecessary limitation, since the cursor positions may still be useful as "marks", even though multicursor is not active.

Use cases:

• allows navigation to the marks; the user can treat the cursors as a generic set of marks, instead of having to manage a parallel set
  • e.g. {op}]C operates on the next mark without cascading.

Expected behavior

]C [C should iterate the nvim.multicursor.last extmarks ?
