blogdown:::update_meta_addin() is incompatible with Rstudio visual mode

[setgree]

Steps to reproduce:

1. start writing blogpost (I usually do this via Rstudio menu options: Serve Site -> New Post
2. write blogpost in visual mode
3. select 'Upate Metadata' -- in Rstudio's Addin buttons
4. get

> blogdown:::update_meta_addin()
Error in rstudioapi::getSourceEditorContext()$selection[[1]] : 
  subscript out of bounds
In addition: Warning message:
The current document does not seem to contain YAML metadata 

5. switch to source mode, it works again

Error in rstudioapi::getSourceEditorContext()$selection[[1]] :
subscript out of bounds

I think this is a problem with all addin using rstudioapi. getSourceEditorContext() does not nicely error when used on Visual Editor mode.

We need to catch the error and nicely error or see if there is a way with rstudioapi to get the associated source file 🤔
