Named filters throw an IllegalArgumentException if they are embedded in an expression

A named filter, one that was added via the configuration API, will throw an IllegalArgumentException if they are embedded in a filter expression.

The following should be a valid expression as "all" is a changed filter and "test" is the manually created filter.

logContextConfiguration.addFilterConfiguration(null, "org.jboss.filter.Test", "test");
logContextConfiguration.getLoggerConfiguration("").setFilter("all(test)");
