Previously, when clearing the pattern by clicking the clear button, the result match list would display a list of empty matches since apparently an empty pattern matches as many times as the subject is long. This is confusing when using the tool. Restructure RegularExpressionDialog::refresh() so that it bails out if the pattern is empty or invalid.
