Loss of Yggdrasil-capable peers when in mesh-only mode

[vartiovaara]

In some instances when connection gets interrupted for a long period of time
in mesh-only mode, I2Pd can not regain connection at default reseed threshold.
This seems to be a symptom of the yggdrasil routers getting dropped, leaving the rest as known.
This can result in a situation where >900 routers are known, but none can do yggdrasil and reseeding
is not triggered resulting in a dead router. This was only fixed by setting the reseeding threshold
above that of the currently known routers and restarting.

i2pd behaves wrong in cases of connection interruption, this is known problem.
You can try adjusting limits.zombies option value.

As for Yggdrasil specific, maybe someone knows more.

Just drop netdb and reseed again.
