False positives for ProvidesMethodOutsideOfModule bug pattern

In Gerrit build we are seeing many false positives for ProvidesMethodOutsideOfModule bug pattern.

For example, we have changed from single injection to multiple injections in this CL: [1]

```diff

```

After the above change we are starting to see this error (that we demoted to warning severity):

```bash

Another example of occurrence of this false positive:

```bash

The above error is reported for this code: [2] and the code works and looks just fine to me.

Gerrit Code Review is using Bazel 6.1.2 with latest java_tools v12.1 that is shipping ErrorProne 2.18.

To reproduce, clone [Gerrit](https://gerrit.googlesource.com/gerrit) recursively and run: `bazel build java/com/google/gerrit/server:server`.
