Comment isn't flattened in template def AST

[ire4ever1190]

Description

Comment nodes are not flattened when they are the single child inside a statement node when in a template definition. They are flattened inside other routine definitions like macros and procs

Example

import macros

template test(docs) =
  proc foo() =
    docs
    discard

  template bar() = 
    docs
    discard
  
macro dump(x: typed) =
  echo x.treeRepr

dump:
  test:
    ## Some documentation
