This seeks to fix the intermittent failure of the "MatrixClient rehydrated from
stored credentials" tests.
The problem appears to be that the 'load_completed' is sometimes taking a while
to come through from the dispatcher - or rather, it is taking a long time to
get *sent* to the dispatcher: the chain of `q().then().catch().done()` in
componentDidMount can take a while to happen.
As a workaround, give the test a few goes when waiting for us to start
syncing. It's not ideal to be poking into the internal state of MatrixChat like
this, but it'll do for now.
The promise would resolve immediately, nulling out `flushPromise`. This would
then immediately be set from `new Promise((resolve, reject) => {...})` turning
it back into non-null `flushPromise`. The resolve handler was called so the
next `flush()` would see "oh yes, there is a non-null `flushPromise`" then
promptly try to set `flushAgainPromise` which chains off the resolved
`flushPromise` which relied on `flushPromise` being `null`ed out after
`resolve()`, causing the chained `flush()` to see "oh yes, there is a non-null
`flushPromise`" which... ad infinitum.
This PR fixes it by making the nulling out asynchronous but the fact it took
me this long to debug this issue indicates to me that this is a terrible piece
of code. Will re-write.
This makes it easier to get a list of all the log IDs. It also makes it possible
to order the logs by the *LAST* log line and not the first as was the case
previously, which is important in the case of long-running tabs.
This has to be relative, because we don't know if riot is going to be mounted
at the top-level of the domain or not (it's not, on riot.im).
Links are relative to the final location of the CSS, which is under
bundles/<hash>, so need ../..
So launching a new instance will focus the old one, meaning that
if you have Riot minimised to the tray and launch it via the
desktop shortcut / start menu, you don't end up with more & more
copies of the app.
This doesn't really prevent you from running multiple copies of
the app to fake multi account support since they share a data
directory anyway.
