When passing only 'project', the build incorrectly assumes 'target' = ES3

[timhurkmans]

typescript({
        project: "tsconfig.json",
}

Results in:

--module commonjs --target ES3 --project tsconfig.json

Expected:

--project tsconfig.json

Workaround:

typescript({
        project: "tsconfig.json",
        target: "ES5",
}

Results in:

--module commonjs --target ES5 --project tsconfig.json

It messes up my code as tsconfig.json can define another module and target, and I don't want to duplicate the options.
