We don't want that the reject cb takes the position of an optional
argument that has not been defined
For example the Dialogs.alert method takes an optional 'buttonLabel'
string. In case we do not set this value, and thus want to use the
default value, the 'reject'
callback get spliced into this position due the fact that the splice
start index is bigger than the array length.
Dialogs.alert("title", "message", "My button text") --> args =
["title", resolve, "message", "My button text", reject]
Dialogs.alert("title", "message") --> args = ["title", resolve,
"message", reject] --> reject is on the position of the buttontitle!
The cordova-plugin-dialogs alert function receives the wrong arguments
—> alert: function(message, completeCallback, title, buttonLabel)
The buttonLabel will receive the "reject" callback instead of a
undefined value.
