Using `multiple: true` in combination with `alias`

[dan-covaliu]

From the readme file examples, if we use the alias 'e' for the excludePaths?: string[], then when we run

$ node exampleConfig.js --sourcePath source --targetPath target --filter src -e=one -e=two
we get an error. Though
$ node exampleConfig.js --sourcePath source --targetPath target --filter src -e one two
seems to work
