Subject: [PATCH] fix: Unchecked error in std.manifestYamlDoc().

Problem: A recursive call within manifestYamlDoc() might fail but the
return value is not checked.

Reproducible with:
```
$ jsonnet-2f73f61 -e "std.manifestYamlDoc({ x: { y: error 'foo' } }, quote_keys=false)"
"x:\n  "
```

Expected:
```
$ jsonnet-0.20.0 -e "std.manifestYamlDoc({ x: { y: error 'foo' } }, quote_keys=false)"
RUNTIME ERROR: foo
	<cmdline>:1:31-42	object <anonymous>
	...
```
