[LitElement] Default array values not extracted

[kylewelsby]

Components that are written with array input do not out-put the programmed default values in the properties table.

Example code

class MyComp extends LitElement {
  /**
   * should render default values
   */
  @property({
    type: Array
  })
  myArray = ["value"]
}

Expected output

Property	Attribute	Type	Default	Description
myArray	myArray	string[]	["value"]	should render default values
