Subject: [PATCH] Fix default values of snapToEnd and snapToStart in
 ScrollViewProps

Summary:
Changelog: [internal]

Default value for `snapToEnd` and `snapToStart` was incorrect in Fabric. This makes no practical difference as default value is never used (JavaScript always sets true or false).

Default value of `snapToEnd` is true.

Default value of `snapToStart` is true.
