The `wrap selections in tag` action currently did not take line_mode
into account, which means when selecting lines with `shift-v`, the
start/end tags would be inserted into the middle of the selection (where
the cursor sits)

This PR fixes this behaviour by checking if the selection uses line_mode
and then adjusting start and end points accordingly.

NOTE: I looked into amending the test cases for this, but I am unsure
how to express line mode with range markers. I would appreciate some
guidance on this and then I am happy to add test cases.

- Fixed `Editor: wrap selection in tags` when in vim visual line mode
