Expected Behavior

The dist folder should be cleaned before a build

Current Behavior

When you build your app when a dist folder allready exists, all old files which may not be part of the application anymore, still remains in the dist folder and will be part of the new build.

Steps to reproduce the issue

1. Build an app with ui5 build
2. Delete a file from you app (e.g. a controller/view)
3. Build the app again
4. Deleted file still part of dist folder

Context

• UI5 Module Version (output of ui5 --version when using the CLI): 1.5.4
• Node.js Version: v10.16.0
• npm Version: 6.9.0
• OS/Platform: Windows 10
• Browser (if relevant): Chrome

Affected components (if known)

• ui5-builder
• ui5-server
• ui5-cli
• ui5-fs
• ui5-project
• ui5-logger

If this behaviour is supposed to be like this, is there a way to clean the dist folder before the execution of the actual build, without using Grunt or something else?
