UIElement `hasWords` assertion occures `PatternSyntaxException`
**Describe the bug**
Given is the Element `<label for="inputMillis"> TimeOut in Millis (0-inf) </label>`

**To Reproduce**

````java
element.expect().text().hasWords("TimeOut in Millis").is(true); // --> passed
element.expect().text().hasWords("TimeOut in Millis (0-inf)").is(true); // -->java.util.regex.PatternSyntaxException: Unclosed group near index xx
````

**Expected behavior**
The second assertion should passed, too.

**Actual behavior**
The method `DefaultStringAssertion.hasWords()` cannot handle special characters like `(`, because there is no escaping. The pattern matcher take the `(` for grouping.

**Solution**
Escape the characters like `(`, `)`, `[`, `]`, ...

**Environment(please complete the following information):**
