Fix Issue #1038 - "User tag autocomplete message area blocks text input" (#1111)

Fix Issue #1038

Fix:

-Cursor in a post/reply now remains visible (regardless of initial location) even when the search/autocomplete view `UserSearch` is present

Change:

-Conditionally set the `.isScrollEnabled` of `TextViewWrapper`(ie, default =true; and =false only when `UserSearch` is present)
