Unescape any character following a backslash. This fixes autocompletion
for names with escaped spaces.
For example: `/msg Thor\ Odinson hello`

Autocompletion failed for nicknames using non Latin scripts. We used
`g_str_to_ascii`, which replaces characters it cannot transliterate with
'?', leading search failures and false matches between different
scripts.
Now we do:
Use `g_utf8_casefold` for case-insensitive UTF-8 comparison. This
ensures that like 'Σ' correctly match 'σ' across all Unicode scripts,
providing correct results for non English nicknames.
If we don't fine anything typing a base ASCII character matches an
accented one (typing `e` matches `è`). This pass uses `g_str_to_ascii`
followed by `g_ascii_strdown` for comparison. It is now restricted to
run if the search string itself is valid ASCII, preventing the
"everything matches '?'" bug in non Latin scripts.
Autocomplete items are sorted using `strcmp`. `g_utf8_collate` provides
linguistical ordering for a specific language. But its behavior is
locale dependent and undefined when comparing strings from different
scripts. `strcmp` does byte-wise ordering that correctly follows Unicode
code order for UTF-8 strings.
Use a behavior-driven naming convention for unit tests.
Functions are now named using the pattern: [unit]__[verb]__[scenario]
The __ works as a semantic separator.
Examples:
* jid_create__returns__null_from_null()
* cmd_connect__shows__usage_when_no_server_value
Benefits:
* Easy to find all tests associated with a specific function using the
mandatory prefix.
* Test output in CI now explicitly describes the unit, the expected
outcome, and the scenario being tested.
Also disabled keyhandlers tests due to missing code in src/ui.
For example cmd_account() is located in src/command/cmd_funcs.c.
The unit test was located in tests/unittests/test_cmd_account.c.
Let's move it to a subdirectory like tests/unittests/command/test_cmd_account.c
to correpsond to the same structure.
