Bare ground establishment problem and increased soil moisture #994

This issue is related to discussion #985 . Two changes that improve the lack of bare ground establishment in some grid cells is to initialise the run with large trees rather than seedlings, and to increase initial soil moisture.

I will make a PR with changes that allow for no comp mode to be initialised with large trees.

Soil moisture initialisation is on the HLM side so will need ELM and CLM PRs.

ELM code here:
https://github.com/E3SM-Project/E3SM/blob/b30a6a0cb3e610f80a00cd0fcdbfffab7044df54/components/elm/src/data_types/ColumnDataType.F90#L1619

Not sure about the CLM side.

I suggest changing use_fates_planthydro to use_fates so that higher soil moisture is default for all FATES runs.

Merge remote-tracking branch 'needhamfork/JFN-soilmoisture' into next…
7d23d96 
… (PR #5508)

This PR changes the condition for a higher initial value of soil moisture so that all FATES runs,
not just FATES-Hydro, will be initialized with higher soil moisture.
This is to improve the establishment of forest in bare ground simulations.
See FATES issue here NGEET/fates#994 and discussion here NGEET/fates#985.

[non-BFB] for FATES only
