[chennan47]

Update user's profile page by adding public registrations and preprints. Remove public components.

Changes

Before change:

After change:
User with projects, registrations, preprints and quickfiles view his own profile page:

Another user view a user's profile page who has projects, registrations, preprints and quickfiles

User without any projects, registrations, preprints or quickfiles view his own profile page

Another user view a user's profile page who has no projects, registrations, preprints or quickfiles

QA Notes

1. checkout user's profile page.
   things to check:

• If user has no preprints, preprints widget will still show up but saying "The user has no preprints"

• If user has no public registrations, registrations widget will still show up but saying "The user has no public registrations"

• If user has no quickfiles, quickfiles widget will disappear

@chennan47 Looks good 👍 , but you have a single test failing, https://travis-ci.org/CenterForOpenScience/osf.io/jobs/357552537... There's also a typical elasticsearch fail, but this one is separate.

@chennan47 You still have a test failure but it's appears to be out of date, and no longer part of your PR, so it really should pass. I'm passing this along to @sloria, because it seems like a travis problem.
