This PR fixes the regression tests for the issue fixed in #6931 .
The reason for that is that all of the invalid queries that triggered the regression have become more or less valid syntax in #6933 (they might still fail typechecking).

This is most likely due to an endpoint not producing valid
metrics output, which we should treat the same as a failed
scrape, and thus not spam the application logs with it.

This is taken from #6918. Since we probably won't merge #6918 before
the relase, we have to do this bit of it as it fixes an actual bug
(iso.closeAppend is not called if the append fails because of an error
logging to the WAL).

We can assume that not all target groups are nil in normal scernarios,
so we can create targets[poolKey] outside the loop.

* tsdb: don't allow ingesting empty labelsets
When we ingest an empty labelset in the head, further blocks can not be
compacted, with the error:
```
level=error ts=2020-02-27T21:26:58.379Z caller=db.go:659 component=tsdb
msg="compaction failed" err="persist head block: write compaction:
add series: out-of-order series added with label set \"{}\" / prev:
\"{}\""
```
We should therefore reject those invalid empty labelsets upfront.
This can be reproduced with the following:
```
cat << END > prometheus.yml
scrape_configs:
- job_name: 'prometheus'
scrape_interval: 1s
basic_auth:
username: test
password: test
metric_relabel_configs:
- regex: ".*"
action: labeldrop
static_configs:
- targets:
- 127.0.1.1:9090
END
./prometheus --storage.tsdb.min-block-duration=1m
```
And wait a few minutes.

This fixes an issue where the /new/targets page will not load when there
are jobs with invalid CSS characters in them, such as the
namespace/service/0 form used by the Prometheus Operator.
