setCustomAutocompletion does not work with keepCurrentCompleters=true

[rappenze]

Describe the bug
I tried to add more than one custom auto completion category by calling the method several times. But only the last call is transfered to the client side.

To Reproduce
Add the following code:

AceEditor aceEditor = new AceEditor();
aceEditor.setMode(AceMode.sql);
aceEditor.setCustomAutocompletion(Arrays.asList("User", "Role"), "table", true);
aceEditor.setCustomAutocompletion(Arrays.asList("FullName", "Address", "Right"), "column", true);
aceEditor.setAutoComplete(true);

Expected behavior
I expect that auto complete shows all values, but only values with category "column" are shown.

@rappenze thanks for the issue

I was able to reproduce it and found why and where it happens. I'll try to build a hotfix asap.
