Fixed code for the Uri as it includes the period at the end as the part of Uri parsing previously.

As for example:
```
A crash report has been written to /Users/andrewkolos/Desktop/asset_transformers_test/flutter_03.log.
``` 

Many terminals are unable to follow the link because it includes the period in the end as part of it. This PR simply removes the period in the end so that it is clickable in many systems (e.g. by `alt` -clicking on it in an embedded bash terminal, VSCode).

```
A crash report has been written to /Users/andrewkolos/Desktop/asset_transformers_test/flutter_03.log
```
