Bug Description:

Currently, we use more than one lib for debouncing:

• theia/packages/debug/src/browser/debug-configuration-manager.ts

  Line 22 in f8bcc19

  import debounce = require('p-debounce');

• theia/packages/core/src/browser/common-frontend-contribution.ts

  Line 19 in f8bcc19

  import debounce = require('lodash.debounce');

Pick one and use that.
