Guard analysis server against missing .instrumentation directory location on disk

Currently if analysis server fails to resolve this directory, it will
crash the entire process with

NoSuchMethodError: The method 'getChild' was called on null.

_readUuid() was already failing over to generating a new random
identifier if it was either unable to find a uuid.txt file or
create one, so this change just triggers that behavior additionally
in the case that the parent directory is missing.
