Make the change to ContextRoot non-breaking.

In 4cf51e6c1afd4d7863e1c0572a74a44b5269b106, a new argument was added
to the ContextRoot constructor, changing its signature in a breaking
way.

In theory this should not have broken other packages, because
ContextRoot is declared inside analyzer/lib/src.  But it turns out
that two packages are known to import from analyzer/lib/src and
construct ContextRoot: angular_analyzer_plugin and
built_value_generator.  To avoid breaking these packages, we need to
add the new constructor parameter as an optional (named) parameter.

Some time after after angular_analyzer_plugin and
built_value_generator have been updated, I'll send a later CL to mark
the named parameter as @required.
