gradle plugin should not throw an error if a version is not found

[rbellamy]

Describe the bug

If there is no version property found, the gradle plugin throws an error.

To Reproduce

auto/plugins/gradle/src/index.ts

Line 80 in 38a12a8

throw new Error("No version was found in gradle properties.");

auto/plugins/gradle/__tests__/gradle.test.ts

Lines 41 to 46 in 38a12a8

	test("should throw when no version", async () => {
	exec.mockReturnValueOnce("");
	await expect(hooks.getPreviousVersion.promise()).rejects.toThrowError(
	"No version was found in gradle properties."
	);
	});

Expected behavior

Like the npm plugin, if it cannot find a version, it should return "0.0.0.0". No error should be thrown.

I would like to contribute. Can I please be assigned to this problem?

Feel free to submit a PR. I don't like assigning them because during hacktoberfest a lot of people call "dibs" but few usually follow through

@hipstersmoothie doesn't #1396 already fix this ?
