File Explorer/Navigator does not watch deleted/added files

Hi,

I think there is an issue in the latest Theia 1.27, it does not refresh the files tree when adding new files or deleting one to/from the workspace. When pressing the Refresh icon on the top of the tree the files are updated correctly.

In version 1.26 all is working as expected.

Using Theia 1.27
Window 10
Browser Chrome
