Versions.

keycloak-angular 7.3.0
angualr 9.1.1
keycloak-js 9.0.2

Repro steps.

It seems there is a regression from version 7.2.0 to 7.3.0.
The reproduction is straightforward, do a GET request using angular HttpClient expecting the bearer token to be added automatically.

The injection (and subsequently the request) fails.

The log given by the failure.

ERROR TypeError: You provided '() => Object(tslib__WEBPACK_IMPORTED_MODULE_0__["__awaiter"])(this, void 0, void 0, function* () {
            const token = yield this.getToken();
            return headers.set(this._authorizationHeaderName, this._bearerPrefix + token);
        })' where a stream was expected. You can provide an Observable, Promise, Array, or Iterable.

Hi @ermannob, thank you for reporting the issue.
Version 7.3.1 is now released and includes the fix for this issue.

Sorry for breaking this guys, looks like I missed this method during my testing. @mauriciovigolo I'll try to add some more tests as I refactor the code.
