status-bar tabs lose configuration after Atom restart

[JeanMertz]

The above picture shows my current configuration.

This works as expected:

• no tabs are shown at the status-bar
• no inline tooltip
• error is shown in bottom error pannel when I move my cursor to a line with an error

After restarting Atom, the following happens:

• configuration is still exactly the same as above
• the same error is shown as if it was on the active line, however that line isn't active, and in fact that file isn't active.
• it looks like it is showing "project wide" errors, however it is not, since the filename isn't appended to the error message, which it normally is in project-wide errors.

Only way to fix this:

• enable "show line tab in error panel"
• click on "Line 0" button to enable it
• disable "show line tab in error panel"
• things now work as expected again
