Updating ember-template-imports breaks test in gjs-gts-processor-test.js

[nlfurniss]

This test fails when ember-template-imports was upgraded from 3.1.1 to 3.1.2.

If the scenario is changed to look like this:

  {
    filename: 'my-component.gjs',
    code: `
-      const Foo = <template>hi</template>
+     const Foo = <template>"hi"</template>
      <template>
        <Foo />
      </template>
    `,
  },

then the test passes, though it is not yet clear why.
