fixed recorder label not updating when project is changed

[Variable-ind]

the recorder label wasn't updating when:

• we changed project (with both projects recording)
• when the recording was just started (the text of label is meant to be empty at that point)

also changed the recorder icon (to a slightly higher resolution one), the old icon was somehow not being displayed correctly (see image below)
