The strings produced by these tests can run to thousands of characters,
which makes test logs difficult to read.

The definition of histograms in the test framework may create
histograms in a non-compact form. Since histogram comparison relies on
exact equality of the bucket layout, we have to compact the histograms
created by the test framework language before comparing them to
histograms returned from the PromQL engine.

Restrict the capacity of first argument to `append()` to force an allocation.
This is for the slice implementation only.

* TSDB: Don't compact the head block when empty
Don't compact the Head block if there have not yet been any samples
appended.
Previously, the logic for determining if the head should be compacted
relied on the default values for min and max time and integer overflow
when they were checked in `Head.compactable()`. The check in
`Head.compactable()` effectively did `math.MinInt64 - math.MaxInt64`
which overflowed and wrapped to `1`. Since `1` is less than `1.5`
times the chunk range, compaction did not happen. This was the correct
behavior but relying on overflow wrapping is surprising.
This change add a method for checking if the min and max time for the
head is unset and uses it to short-circuit compaction in that case.
It also replaces several explicit checks for the default value to
determine if the head has not yet had any samples added.
