QRegularExpression example: Handle empty patterns
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.
