Florian Schmaus 89c0fa4b99 Let StringUtils.(insecure)randomString() return empty string
in case length is zero. Also do throw a NegativeArraySizeException if
length is negative instead of returning null.

This fixes the following sporadic test issue:

org.jivesoftware.smackx.ox.PainlessOpenPgpProviderTest > encryptDecryptTest FAILED
java.lang.AssertionError
at org.jivesoftware.smack.util.XmlStringBuilder.escape(XmlStringBuilder.java:425)

at org.jivesoftware.smackx.ox.PainlessOpenPgpProviderTest.encryptDecryptTest(PainlessOpenPgpProviderTest.java:155)

because EncryptedOpenPgpContentElement rpad field was sometimes
'null' in case the random function returned '0' as length.
