Accessibility: Remove redundant `title` attributes Part 2

[mercime]

Second pass at removing redundant title attributes. See #7090.

Attached images with the delete mark are the targets for this ticket: Log in, Recent Networkwide Posts, Groups, and Friends widgets along with some found in the Messages, Notifications, and Activity screens.

The other title attributes which provide additional information for text links, group/member avatars, etc. will be addressed in #7188 (​http://codepen.io/mercime/pen/vygMEg)

Attached patch removes redundant title attributes from links as well as from all avatars which already have alt attributes read by screen readers.

Looks good to me.

Leaves off removing title attr from bp_core_get_userlink to double-check

Thanks @netweb.

Hi @boonebgorges I had to remove the title attributes from avatars, all of which already have alt attributes, to avoid extra noise to users of screen readers. Attached 7363-tests.patch removes the tests for the title attributes in blog avatars. For your approval.

One more redundant title attribute

[mercime]

Removal of title attr is good to go

[boonebgorges]

Tearing out the tests as in 7363-tests.patch​ seems fine to me.

[mercime]

Thank you @boonebgorges. Committing the patches in a few minutes.

In 11385:

Accessibility: Remove redundant title attributes from user and message links.

See #7363.

[mercime]

In 11386:

Remove unit tests for title parameters in blog avatars.

The unit tests are no longer needed because we have removed title
attributes from blog avatars in r11381.

Fixes #7363.
