There was never a need to initialise them there in the first place. In fact, an external variable is effectively an algebraic variable which is computed by an end user. So, it needs to be computed in computeRates() (if available) and in computeVariables().

Also fixed an issue with initialiseVariables() not always including the VOI.

Oversight on my part!

This effectively reverts commit b1b7536.

Indeed, some computed constants are initialised using an equation (e.g., x = 3 rather than x with an initial value of 3). So, there is no need to compute those computed constants many times (using computeComputedConstants()). Instead, it's much better to compute them in initialiseVariables().

Not to mention that we might have "computedConstants[1] = 1.0;" and then "computedConstants[0] = computedConstants[1];" so if we were to compute both of them in computeComputedConstants(), we would need to compute "computedConstants[1] = 1.0;" before computing "computedConstants[0] = computedConstants[1];", which would make things slightly more complicated to generate.

This is so that we can test an algebraic model with an external variable (in https://github.com/agarny/libCellMLGeneratedCodeTests).
