BrighterScript template strings silently fail in annotations

[fastfrwrd]

I wanted to use a BrighterScript template string in a @params annotation for a test I was writing, but found that when I used the template string within the annotation, the test run unexpectedly hung on the device and never completed or exited with an error.

Test case to reproduce:

namespace Testing.TemplateStringsInAnnotations

    @suite
    class TestCase extends Rooibos.BaseTestSuite

        private data as object

        '+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
        @describe("test case")
        '+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

        @it("should be able to test BrighterScript template strings")
        ' this works fine, of course...
        @params("foo")
        ' ... but this one doesn't, and silently fails while the tests run on-device.
        @params(`foo`)
        function _(input as string)
            m.assertEqual(input, "foo")
        end function
    end class

end namespace
