Minor inconsistency in output of lambda()

[Aariq]

A very minor inconsistency, but the output of lambda() on a deterministic IPM is a named vector and the output on a stochastic IPM is unnamed.

lambda(ipm_det)

#    lambda 
# 0.9790214 

lambda(ipm_det_ff) %>% names()
# [1] "lambda"

lambda(ipm_stoch)
# log(lambda) is returned by default for stochastic models. Set 'log = FALSE' for lambda on linear scale.
# [1] -0.02078642

lambda(ipm_stoch_ff) %>% names()
# log(lambda) is returned by default for stochastic models. Set 'log = FALSE' for lambda on linear scale.
# NULL

hm, that is not great - sorry about that. I'll get to this when I address #50

Believe this is fixed now as well, but let me know if you still have issues!
