force:source:retrieve -x ... doesn't update static resources

[ChuckJonas]

Summary

force:source:retrieve will pull down static resources, but it does not update them.

Steps To Reproduce:

1. Create a static resource called broken.txt with the text: Hello World
2. Create a dx manifest project connected to the org
3. run sfdx force:source:retrieve -x manifest/package.xml
4. Confirm the broken.txt was retrieved and contains Hello World
5. upload a new version of the broken.txt via salesforce.com (not via local compile), that reads goodbye world
6. run sfdx force:source:retrieve -x manifest/package.xml

Expected result

The local copy of broken.txt should be updated to read goodbye world

Actual result

The local copy of broken.txt still reads hello world

@Pflaumen we've created a work around for this in https://github.com/ChuckJonas/force-source-clean

(although make sure you understand the "clean" behavior before running it)
