Mismatch between contents of the left-hand file tree view and right-hand directory view

[evansd]

When the content of a workspace changes the right-hand directory view will automatically update if you click between different directories. But the left-hand file tree view will never update.

Here's a screenshot from a local reproduction of the issue:

To reproduce:

• I opened subdir_1 in the left-hand tree view.
• I created a new workspace file with touch workdir/workspaces/example-workspace_1/sub_dir_1/daves_file.txt
• I clicked subdir_2 and in the left-hand view and then back to subdir_1.

This inconsistency compounded the confusion caused by these other two issues:

• Potential mismatch between file contents and metadata #1044
• Old versions of excluded L4 files are left in place, causing confusion job-runner#1289

So I just needed to refresh airlock?? But I don't really want to have to refresh airlock everytime. And anyway, some of the files did appear as expected, after rerunning. So no reason to think I'd need to refresh
