extract_objects on an internal dependency crashes

[QuLogic]

Describe the bug
If you call declare_dependency(link_with:...).extract_objects(...), then Meson crashes.

To Reproduce
Add this line to the test case:

diff --git a/test cases/common/80 declare dep/meson.build b/test cases/common/80 declare dep/meson.build
index e427defaf..761a92478 100644
--- a/test cases/common/80 declare dep/meson.build
+++ b/test cases/common/80 declare dep/meson.build
@@ -6,6 +6,7 @@ exe = executable('dep_user', 'main.c',
   dependencies : entity_dep)
 test('dep', exe)

+entity_dep.extract_objects('entity1.c')
 # just to make sure [] works as a no-op dep here
 executable('dummy', 'main.c',
   dependencies : [entity_dep, []])

then run meson.py setup 'test cases/common/80 declare dep' build, which produces this exception:

meson.build:9:27: ERROR: Unhandled python exception

    This is a Meson bug and should be reported!

Expected behavior
A clear error that this is not supported.
