mod_http_muc_log: Fix exception on lack of trailing slash in room path
A request to /room leads to the match call returning nil which in turn
calls nodeprep(nil). In Prosody 0.11.x this does nothing and simply
returns the nil, while in 0.12 it is an error.
Now it redirects to the calendar view at /room/ - even for non-existant
rooms.
Discovered at a deployment with http_paths = { muc_log = "/" } and
requests to /robots.txt and similar, which now result in a uses redirect
before returning 404.

16 First, download and add the module to `module_enabled`. Then you can |
1842 | 17 decide on what policy you want to have. |
18 | |
19 Requiring ciphers with forward secrecy is the most simple to set up. | |
20 | |
21 ``` lua | |
22 tls_policy = "FS" -- allow only ciphers that enable forward secrecy | |
23 ``` | |
24 | |
25 A more complicated example: | |
26 | |
27 ``` lua | |
28 tls_policy = { | |
29 c2s = { | |
30 encryption = "AES"; -- Require AES (or AESGCM) encryption | |
31 protocol = "TLSv1.2"; -- and TLSv1.2 | |
32 bits = 128; -- and at least 128 bits (FIXME: remember what this meant) | |
33 } | |
34 s2s = { | |
35 cipher = "AESGCM"; -- Require AESGCM ciphers | |
36 protocol = "TLSv1.[12]"; -- and TLSv1.1 or 1.2 | |
37 authentication = "RSA"; -- with RSA authentication | |
38 }; | |
39 } | |
40 ``` | |
41 | |
