Fix shortcut CTRL-l to create alias link from page link

Ctrl-l can create links to both external URLs as well as other pages:
[my link](
[my page link]([[my page]])

Given an existent link [[my page]], it would be nice for alias creation to have correct autocomplete. When visually selecting page link and and pressing crl-l, currently this happens:
[[[my page]]]()

Expected: []([[my page]])
