Bug 543895: [GTK] Extra space to the right of ToolItems without text

Only set a ToolItem as "important" if it actually has text. Otherwise
this ToolItem will show its label even if no text is set, causing
extra padding.

Tested on GTK3.24 with the snippet attached. NoAllNonBrowser JUnit
tests fail.
