fix(karma): error messages truncated due to custom formatter

Currently error messages printed out by Karma will be truncated
sometimes. This can happen for example if a jasmine test assertion
contains parenthesis characters. For example:

```ts
expect(element.style.transform).toBe('translate3d(...)')
```

If such an assertion fails, the error message from the browser
looks like that:

```
        Error: Expected 'translate3d(50px, 100px, 0px)' to be 'translate3d(500px, 100px, 0px)'.
            at <Jasmine>
            at UserContext.eval (../../src/cdk/drag-drop/directives/drag.spec.ts:79:44 <- bin/src/cdk/drag-drop/directives/drag.spec.js:104:57)
```

Currently the format error function that is supposed to clean up paths in the error message, accidentally
matches the first path starting with `(50px, 100px, 0px` and ending with `drag.spec.ts:79:44`). Resulting in
a broken error message like:

```
        Error: Expected 'translate3d(../src/cdk/drag-drop/directives/drag.spec.ts:79:44 <- bin/src/cdk/drag-drop/directives/drag.spec.js:104:57)
            at UserContext.eval (external/npm/node_modules/zone.js/dist/zone-testing-bundle.js:4954:30)
            at ZoneDelegate.invoke (external/npm/node_modules/zone.js/dist/zone-testing-bundle.js:391:26)
```
