toUpperCaseURL does not produce the expected output from official RML-FNML test cases

[s-minoo]

The official RML-FNML test cases utilizing idlab-func:toUpperCaseURL expect the generated output of the function to have a lower-case http instead of the upper case HTTP as returned by the current implementation

idlab-functions-java/src/main/java/be/ugent/knows/idlabFunctions/IDLabFunctions.java

Lines 230 to 236 in 841eb8d

	public static String toUpperCaseURL(String test) {
	String upperTest = test.toUpperCase();
	if (!upperTest.startsWith("HTTP://")) {
	upperTest = "HTTP://" + upperTest;
	}
	return upperTest;
	}

Which one should be the correct output?

It's even better: some test cases using this function have a result starting with http, others with HTTP.
