Check all targets do not work on new files

[linards-kalvans]

When I set Check all targets = 'On' in Rls Configuration, I get results from compiler on all my valid *.rs file targets, though when a new file is added that also is a valid target, there is no analysis there until I disable and re-enable the configuration option.
