Jake Klinker 6e0ca56095 Fix isFileUri to recognize URIs with spaces.
The underlying framework recognizes " file://..." as a valid URI and fetches the file, allowing for a possible exploit (see b/209965112). This trims the URI so that we can properly recognize it as a file from within our code.

Jake Klinker 56bacbcb13 Convert URI scheme to lower case before checking if it is a file.
This fixes an edge case where a "File://" style URI could be passed in
but not pass this check, even though the underlying framework recognizes
this as a legitimate file.
