Template `${\ }` causes NullPointerException in Lexer.innerNextToken

[kreiger]

With template ${\ } (escaped space), Lexer.innerNextToken throws NullPointerException

java.lang.NullPointerException: Cannot invoke "String.contains(java.lang.CharSequence)" because "variableName" is null
	at com.floreysoft.jmte.token.Lexer.innerNextToken(Lexer.java:245)
	at com.floreysoft.jmte.token.Lexer.nextToken(Lexer.java:21)

This is because variableName is null at

if (variableName.contains(" ")) {
	return new InvalidToken();
}

... because Util.MINI_PARSER.greedyScan(completeDefaultString, "(", ")") return an empty List when completeDefaultString is "\ ".
