methods on custom structs defined inside macros are not deleted on re-run

[disberd]

I noticed that when using macros to generate block of code that contains custom struct and custom methods defined on those, older methods are not deleted upon re-run. This is not the case when the same codeblock is directly put in a cell rather than inside a macro.

This also creates another instance of the duplicated docstrings (if they are also present in the macro body) like in closed issues #1708 and #1932.

Tagging @Pangoraw directly as he is the macro wizard

Here is a video example:

and here is the notebook code:

I guess that's also why memoized functions from Memoize.jl are not deleted either.
