Now that all casper tests have been migrated to
puppeteer, there's no need for having casper
related things.
Removed the casperjs package and removed/replaced
casper in few places with puppeteer.
Only removed few of them which I'm confident
about. Also didn't make any changes in docs
as it would be easier to remove them while
adding puppeteer docs.
These `waitForSelector`s appear just after page loads.
Though they worked most of the times, a few clicks weren't
getting registered because of these selectors not appearing
and thus causing flakes as the modal takes time to appear.
Adding visible: true asserts that it's visible and not just present.
In few rare cases the click on display settings section wasn't working
which was causing the test to stay in the "your account" settings section.
This lead to a waitFor fail.
The screenshot in this failed CircleCI build suggests the above.

This and the previous commit along with the changes to prevent
logging out of user on changing password were tested by running
this test 1200 times and all of them passed!
We need to replace 'visible: false' with 'hidden: true' to wait
for elements to get hidden. Using 'visible: false' just checks
whether the selector exists or not and does not check whether
the element is hidden or not.
This test changes user password causing all subsequent
tests to fail. Since rechanging the password would be
a redudant test/task or having manually entering the
new password in every test after this aren't good ideas,
this commit makes the settings test run in the end by
renaming it be numbered 16. It is assumed that we'll
end up having 16 tests seeing the number of tests in
casper and considering 03 and 02 from casper are being
combined as 02-message-basics.js. Though 03 of casper
has not yet been added in message-basics test it will
soon be added.
