rust_test doesn't know about the aliases in the library target

With a `rust_library` target that uses aliases, compiling its test target without aliases will fail:
```
rust_library(
name = "bar",
srcs = glob([
"src/**/*.rs",
]),
aliases = {
"//my_project/foo/id": "foo_id",
},
edition = "2021",
deps = [
"//third_party/cargo:chrono",
"//my_project/foo/id",
],
)

rust_test(
name = "bar_test",
crate = ":bar",
)
```
Took a bit time for me to figure out as I was doing `ibazel build //my_project/...` and thought the library target was failing.

Adding the same aliases to the test target work but feel unnecessary. I think the test target should be able to inherit / merge the aliases in the library target.
