Solution:
This is a follow-up to the work done in
6c03601e3a.
There are valid situations where a `textDocument/codeAction` is returned
without a command, since a command in optional. For example from Metals,
the Scala language server when you get a code action to add a missing
import, it looks like this:
```json
Result: [
{
"title": "Import \u0027Instant\u0027 from package \u0027java.time\u0027",
"kind": "quickfix",
"diagnostics": [
{
"range": {
"start": {
"line": 6,
"character": 10
},
"end": {
"line": 6,
"character": 17
}
},
"severity": 1,
"source": "bloop",
"message": "not found: value Instant"
}
],
"edit": {
"changes": {
"file:///Users/ckipp/Documents/scala-workspace/sanity/src/main/scala/Thing.scala": [
{
"range": {
"start": {
"line": 6,
"character": 10
},
"end": {
"line": 6,
"character": 17
}
},
"newText": "Instant"
},
{
"range": {
"start": {
"line": 1,
"character": 0
},
"end": {
"line": 1,
"character": 0
}
},
"newText": "\nimport java.time.Instant\n"
}
]
}
}
}
]
```
This change just wraps the logic that grabs the command in a conditional
to skip it if there is no command.
