[#1661] Make FAST stage 1 resman tf destroy more reliable

[LucaPrete]

It sometimes happens that when the FAST stage 1 TF destroy process breaks half way through, we get some errors on outputs:

Error: Unsupported attribute
│
│   on outputs.tf line 226, in locals:
│  226:     tag_keys         = { for k, v in module.organization.tag_keys : k => v.id }
│     ├────────────────
│     │ module.organization is object with 8 attributes
│
│ This object does not have an attribute named "tag_keys".

While the real cause is still unknown, this patch tries to address the problem tactically, adding some try statements where needed.

I applicable, I acknowledge that I have:
