[lttng-dev] [PATCH lttng-tool] Fix: missing context type string in save for ust context

[Jonathan Rajotte Julien]

Return string for LTTNG_UST_CONTEXT_PERF_THREAD_COUNTER was missing and
caused an error on save when a context of PERF_THREAD_COUNTER type was
present (Error: Invalid parameter).

Fixes #804
