jest/no-identical-title doesn't report if using backticks

[himynameisdave]

Just checked and it appears that jest/no-identical-title doesn't report an error when specifying the title using backticks (even when not using string interpolation).

Error:

describe('an odd case where identical titles are not reported', () => {
    it('this works as expected', () => {
        //  ...test code here
    });
    it('this works as expected', () => {
        //  ...test code here
    });
});

Not reported:

describe('an odd case where identical titles are not reported', () => {
    it(`this does not work as expected`, () => {
        //  ...test code here
    });
    it(`this does not work as expected`, () => {
        //  ...test code here
    });
});

Thank you for the report. It looks like we should also be checking that the first argument is a TemplateLiteral without any expressions (e.g. no ${}) in the following area.

eslint-plugin-jest/rules/no-identical-title.js

Lines 54 to 58 in 3a1dc2d

	if (!isFirstArgLiteral(node)) {
	return;
	}
	const title = node.arguments[0].value;

A PR is welcome - may take a further look at it this weekend, and if so, will comment that I'm picking it up. If you or anyone else would like to submit a PR with a fix, please comment!
