title: Firebase password signup doesn't save user
body: <p>I have used Firebase serval times by now and I am aware to how use it correctly.
  I believe I have been stumble on a bug and would love to hear a solution in case you have one.</p>
  
  <p>So - I used Firebase Google auth and it worked ok, then I decided to use the email + password method.
  Now this is the weird part - I create a user, I get successful result but it doesn't save the user - cant see it in the Autherecation panel + cant sign in with the user after I sign out.</p>
  
  <pre><code> mLoginContainer.setVisibility(View.GONE);
      mLoginProgress.setVisibility(View.VISIBLE);
      mAuth.createUserWithEmailAndPassword(email,password).addOnCompleteListener(new OnCompleteListener&lt;AuthResult&gt;() {
          @Override
          public void onComplete(@NonNull Task&lt;AuthResult&gt; task) {
              if(task.isSuccessful())
                  Toast.makeText(LoginActivity.this,"",Toast.LENGTH_SHORT).show();
              else
                  Toast.makeText(LoginActivity.this,"",Toast.LENGTH_SHORT).show();
              mLoginContainer.setVisibility(View.VISIBLE);
              mLoginProgress.setVisibility(View.GONE);
          }
      });
  </code></pre>
