Similar to the previous commit, the tooltip was not
completely visible in this case and this bug was
similar to the one corrected in recipient bar icons.
Here, the tooltip was partially visible. This bug was similar
to the one that is corrected for recipient bar icons.
I have removed the class attribute `tippy-zulip-tooltip`
for Filter stream title as this will be handled by the
new changes.
This commit migrates the `right_sidebar.html` Django template
to handlebars by creating a new file as `right_sidebar.hbs`
which is then rendered using `ui_init` module.
It also removes the tests in `test_home` due to the template
migration, since these elements aren't rendered on the backend
anymore.
We also remove `test_compute_show_invites_and_add_streams*`.
Fixes part of #18792.
