I don't think yank (non edit) operation should exit_select_mode

[Abdillah]

Based on @the-mikedavis comment, he indicates that exit select mode generally applied after a change action. But yank and yank_main_selection_to_clipboard doesn't do any modification and should retain its mode (whether in select or normal).

Update:
In addition to that,

• expand/shrink_selection
• yank, yank_main_selection_to_clipboard and all non-delete variants
