.Net: Plugin name inside FunctionInvokingContext in th IFunctionFilter is null

[EdenTanami]

Describe the bug
In the function filter we receive the FunctionInvokingContext object and inside it the kernelFunction but for some reason the pluginName attribute inside the function metadata is null
(the kernelFunction that is registered in the kernel has valid pluginName).

To Reproduce
Steps to reproduce the behavior:

1. Write any function filter and register to the kernel.
2. Inside OnFunctionInvoking or OnFunctionInvoked the following value is null:
   context.Function.Metadata.PluginName

Expected behavior
The plugin name will have the same value it has in the kernelFunction that is register in the kernel.
