  Don't crash when UTF-8 conversion of filename in `fetchScriptFromLocalFileSystem` fails

Reviewed by Yijia Huang.

Previously, `fetchScriptFromLocalFileSystem` assumed that UTF-8 conversion of the filename
would always succeed, and had a `RELEASE_ASSERT` asserting such. However, if this conversion
fails for any reason, we'll trip the assertion. This patch cleans up this case by having the
program fail gracefully.
