Fix duplicated roots are shown

Symptom:
Duplicated roots are shown in the drawer of DocumentsUI

Root cause:
ArrayListMultimap that allows duplicate key-value pairs is used for
mRoots. If the specific roots info are re-loaded with getRootOneshot(),
the duplicate roots info are put in mRoots and results in duplicated
roots are shown.

Solution:
Use replaceValues() instead of putAll() when re-loading roots for the
specific authority.
