This commit has been done according to @abperiasamy's feedback as we
are going to reserve the click on file icon to open the preview modal
in the future.
Also, when the user now selects a single file, the file itself is
downloaded instead of a .zip file containing the file.
Fixes#6019
* format js files using prettier
Used the following command to format the files
prettier --write "browser/app/js/**/*.js"
* fix failing unit tests in browser
* conditionally render main action buttons
- Make bucket action will be available only for loggedIn users
- File upload button will be avaialble for loggedIn users
and non-loggedIn users if the prefix is writable
* select the bucket and prefix from the url
When the url contains bucket and prefix, it will be selected
by default instead of the first bucket from the list.
* show BucketSearch only for LoggedIn users
* allow non-LoggedIn users to access public bucket
* removed unused Router imports
* fix test case failures in BucketList.test.js
* remove dupicate minioBrowserPrefix from url
since history is already initialized with minioBrowserPrefix,
no need to use it in push or replace
* remove unused match from App component
* remove unused minioBrowserPrefix imports
