Merged PR 490: Bump Moq from 4.14.7 to 4.15.2

Bumps [Moq](https://github.com/moq/moq4) from 4.14.7 to 4.15.2.

#Changelog

*Sourced from [Moq's changelog](https://github.com/moq/moq4/blob/master/CHANGELOG.md).*

> ## 4.15.2 (2020-11-26)
>
> #### Changed
>
> * Upgraded `System.Threading.Tasks.Extensions` dependency to version 4.5.4 (@JeffAshton, [#1108](devlooped/moq#1108))
>
>
> ## 4.15.1 (2020-11-10)
>
> #### Added
>
> * New method overloads for `It.Is`, `It.IsIn`, and `It.IsNotIn` that compare values using a custom `IEqualityComparer<T>` (@weitzhandler, [#1064](devlooped/moq#1064))
> * New properties `ReturnValue` and `Exception` on `IInvocation` to query recorded invocations return values or exceptions (@MaStr11, [#921](devlooped/moq#921), [#1077](devlooped/moq#1077))
> * Support for "nested" type matchers, i.e. type matchers that appear as part of a composite type (such as `It.IsAnyType[]` or `Func<It.IsAnyType, bool>`). Argument match expressions like `It.IsAny<Func<It.IsAnyType, bool>>()` should now work as expected, whereas they previously didn't. In this particular example, you should no longer need a workaround like `(Func<It.IsAnyType, bool>)It.IsAny<object>()` as originally suggested in [#918](devlooped/moq#918). (@stakx, [#1092](devlooped/moq#1092))
>
> #### Changed
>
> * Event accessor calls (`+=` and `-=`) now get consistently recorded in `Mock.Invocations`. This previously wasn't the case for backwards compatibility with `VerifyNoOtherCalls` (which got implemented before it was possible to check them using `Verify{Add,Remove}`). You now need to explicitly verify expected calls to event accessors prior to `VerifyNoOtherCalls`. Verification of `+=` and `-=` now works regardless of whether or not you set those up (which makes it consistent with how verification usually works). (@80O, @stakx, [#1058](devlooped/moq#1058), [#1084](devlooped/moq#1084))
> * Portable PDB (debugging symbols) are now embedded in the main library instead of being published as a separate NuGet symbols package (`.snupkg) (@kzu, [#1098](devlooped/moq#1098))
>
> #### Fixed
>
> * `SetupProperty` fails if property getter and setter are not both defined in mocked type (@stakx, [#1017](devlooped/moq#1017))
> * Expression tree argument not matched when it contains a captured variable &ndash; evaluate all captures to their current values when comparing two expression trees (@QTom01, [#1054](devlooped/moq#1054))
> * Failure when parameterized `Mock.Of<>` is used in query comprehension `from` clause (@stakx, [#982](devlooped/moq#982))
>
>
> ## 4.15.0
>
> This version was accidentally published as 4.15.1 due to an intermittent problem with NuGet publishing.
