Ivan Trubach 68090d7ff1 Fix empty outputsToInstall for InstallableAttrPath
Fixes assertion failure if outputsToInstall is empty by defaulting to the "out"
output. That is, behavior between the following commands should be consistent:

	$ nix build --no-link --json .#nothing-to-install-no-out
	error: derivation '/nix/store/eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee-nothing-to-install-no-out.drv' does not have wanted outputs 'out'

	$ nix build --no-link --file default.nix --json nothing-to-install-no-out
	error: derivation '/nix/store/eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee-nothing-to-install-no-out.drv' does not have wanted outputs 'out'

Real-world example of this issue:

	$ nix build --json .#.legacyPackages.aarch64-linux.texlive.pkgs.iwona
	error: derivation '/nix/store/dj0h6b0pnlnan5nidnhqa0bmzq4rv6sx-iwona-0.995b.drv' does not have wanted outputs 'out'

	$ git rev-parse HEAD
	eee33247cf6941daea8398c976bd2dda7962b125
	$ nix build --json --file . texlive.pkgs.iwona
	nix: src/libstore/outputs-spec.hh:46: nix::OutputsSpec::Names::Names(std::set<std::__cxx11::basic_string<char> >&&): Assertion `!empty()' failed.
	Aborted (core dumped)
