vim: Fix bug where d . . freezes the editor (#42145)

This bug seems to be caused by pushing an operator (i.e. `d`) followed
by a repeat (i.e. `.`) so the recording includes the push operator and
the repeat. When this is repeated (i.e. `.`) it causes an infinite loop.

This change fixes this bug by pushing a ClearOperator action if there is
an ongoing recording when repeat is called.

Release Notes:

- Fixed bug where pressing `d . .` in Vim mode would freeze the editor.
