From 1.5.0 onwards, dashes don't collapse when extended

[paleite]

1.5.0 broke the behavior when collapsing dashes in some cases:

I use the following test cases.

expect(slugify("day---night")).toBe("day-night"); // Works
expect(slugify("day   night")).toBe("day-night"); // Works
expect(slugify("day + night")).toBe("day-night"); // Broken in ^1.5.0, but working in <=1.4.7, when using extend as described below 

This is how I extended slugify.

slugify.extend({ "+": "-" }); // Broken in ^1.5.0, but working in <=1.4.7

// Note: The following works as expected, however: { "+": " " }

Looks like I broke this in #115.
