Remove redundant click in legislation spec

The link to edit the process is already present before clicking the
"All" link, which meant the test failed sometimes because Capybara might
try to click on the "Edit" link at the same time the page is changing
due to the click on the "All" link".

Due to this issue, this test has failed at least one in our CI [1].
