[BUGFIX] Extbase UriBuilder warning in Backend context

The extbase UriBuilder can be used in backend context,
ActionMenuItemViewHelper does that for instance. The
code accesses $GLOBALS['TSFE'] at one point, which
may not be set.

The ActionMenuItemViewHelperTest triggers this, but
it should be a general asset of UriBuilder to work
without TSFE, so this is not considered an incomplete
test setup, but fixed in UriBuilder directly.

Resolves: #95529
