Error: [#2] Error when removing the label: "Label does not exist"
The quotes on this last line make it look like the action was trying to
remove a label named `Label does not exist`.
This change removes the quotes to make it clear that the text is just an
error message (which is implied by the `:`) as opposed to the name of a
label, which is the reading one gets from the inclusion of additional
quotes around the text.
